Hmm, not sure then - maybe try md5sum on the firmware that dmesg shows loading on each then if different backup/copy over etc. I am just a user so don't know what's different between 3.16 and later. One thing I noticed at one point when setting mine up was (after unknowingly breaking a splitter) that with the degraded splitter I could get working/not on some T2 muxed by flipping the lna on off with the option available with dvbv5-*.
